Injected-field optical bistability model of squeezed coherent light generation

Abstract

We show how the squeezed vacuum fields generated in collective fluorescence within a highfinesse cavity can be transformed into squeezed coherent states with high brightness but with the same degree of noise suppression. The transformation is achieved by an injected signal that creates a mean polarization and squeezing in the high rather than the low branch of the optical bistable collective radiation. Analytical expressions are obtained for the limit of weak excitation of the atomic media. Comparisons with results obtained using rigged-reservoir theories and also from a multistage attenuator are made. The limitations of the model are discussed.

Suppression of fluorescence in a lossless cavity

“…An easy way to obtain this is to first eliminate the classical driving field by transforming p as follows (see also Ref. [18]):…”
